On the east side of Rohault Lake, the lake Bouteroue has a length of 16.9 kilometres (10.5 mi), a maximum width of 2.2 kilometres (1.4 mi) and a maximum of altitude of 402 metres (1,319 ft). The outline of the lake has a complex shape with five parts:

• the northern part of about twenty islands, which receives the waters of Rohault Lake and has a bay to the northeast;
• that part of the east which forms a U-shaped bay (open to the north) with a length of 3.7 kilometres (2.3 mi);
• that part of the West with a peninsula of 2.2 kilometres (1.4 mi) oriented towards the South which gives it the shape of a U (open to the North), receiving the dumps of Lake Madeira, Djebel, Ribemont and Mayac; and also receiving the current coming from the North;
• the central part of a length of 7.1 kilometres (4.4 mi) (North-South axis) receiving the waters of the Pertain, Ivors and Rhea lakes;
• the southern part of a length of 7.6 kilometres (4.7 mi) in the form of a double hook (one North hook is the "Bay of Wisdom" and the other hook, the bay of the mouth of the lake ), receiving the discharge from Finbar Lake.

The mouth of lake Bouteroue is located at:

• 5.7 kilometres (3.5 mi) south of the mouth of Bouteroue Creek (confluence with the Normandin River);
• 6.9 kilometres (4.3 mi) northwest of the mouth of Poutrincourt Lake;
• 27.1 kilometres (16.8 mi) west of the mouth of the Normandin River (confluence with Ashuapmushuan Lake);
• 148.1 kilometres (92.0 mi) northwest of the mouth of the Ashuapmushuan River (confluence with Lac Saint-Jean);
• 188.8 kilometres (117.3 mi) west of the mouth of lac Saint-Jean (confluence with the Saguenay River).[1]

The main hydrographic slopes near Lac Bouteroue are:

• North side: Nicabau Lake, Coquille River (Normandin River), La Dauversière Lake, Énard River, Chibougamau Lake;
• East side: Chaudière River (Normandin River), Normandin River, Bouteroue Creek, Nicabau Lake;
• South side: Buade Lake (Normandin River), Poutrincourt Lake, Marquette River West, Ventadour River, Titipiti River;
• West side: Rohault Lake, Nemenjiche Lake, Opawica River, Gabriel Lake (Opawica River), Surprise Lake (Roy River), Cawcot River.

From the dam at the mouth of Bouteroue Lake, the current flows down Bouteroue Creek to a bay at

South of Nicabau Lake. The latter is mainly fed by the Boisvert River (Normandin River) (coming from the North) and the Normandin River (coming from the South). The Normandin River flows southeast to Ashuapmushuan Lake which is the head lake of the Ashuapmushuan River.
